check_mix | Decides whether two songs will mix well, from their keys and BPMs, using the Camelot wheel and DJ tempo limits (about 3% sounds natural, up to about 16% is usable, half and double time count). Returns a verdict, the tempo change in percent and the target BPM for track B, the smallest key shift in se |
camelot | Gives the Camelot wheel code for a key and the three other keys that mix cleanly with it (one step either way with the same letter, and the relative major or minor). |
tempo_change | Percent change and playback rate to go from one BPM to another, how noticeable it will sound, the pitch change if it is not time-stretched, and the half and double time of the target. |
speed_pitch | For a nightcore (faster and higher) or slowed (slower and lower) version: the pitch change in semitones for a speed, the new BPM if given, and typical settings. Defaults: nightcore 1.25x, slowed 0.80x. |
transpose | Moves a key up or down by semitones and gives the new key name and Camelot code, with a note on how natural the shift will sound. |
song_report | Reads the song DNA from a MusicMind report the person made on zeltorlabs.com and shared: key and Camelot code with the keys that mix with it, BPM, genre mix, section structure with energy, and production DNA (energy profile, mood, arrangement density, compression, biggest moments).
